MPI
MPI (Message Passing Interface) is a standardized and portable message-passing system designed for parallel computing, enabling communication between processes in distributed-memory systems. It provides a library of routines for tasks like point-to-point and collective communication, synchronization, and data distribution, widely used in high-performance computing (HPC) for scientific simulations and large-scale data processing.
Developers should learn MPI when working on parallel applications that require efficient communication across multiple processors or nodes, such as in scientific computing, climate modeling, or financial simulations. It is essential for scaling computations on clusters and supercomputers, offering high performance and portability across different hardware architectures.
